| 摘 要： | 为了解我国黄淮海以及长江流域麦区主推品种及二线材料的抗白粉病性，2008-2010年度在武汉病害鉴定圃对来自黄淮海以及长江流域的408份品种（系）进行了抗白粉病的鉴定。R型聚类分析结果表明，利用表观侵染速率、毒力频率、病程曲线下面积和最后一次病指对白粉病抗性进行评价只需前两个指标即可。根据建立的评价标准，绵麦37两年均对白粉病免疫，绵麦39等15份材料两年均表现高抗，扬麦13等46份材料两年均表现中抗。

| Abstract: | The powdery mildew disease caused by Blumeria graminis f.sp.tritici is one of the most important diseases in wheat.To screen better multi-resistance germplasm and provide useful information for rational utilization of varieties,the resistance to powdery mildew of 408 cultivars and high-generation breeding lines,which came from the Huang-Huai-Hai as well as the Yangtze River basin,were evaluated and identified at Wuhan,Hubei in 2008-2010.Apparent infection rate,virulence frequency,area under disease progress... |
